FZ who m it may concern:

Be it known that i, Annex-vi Tonnnnu, e cisizen of ihe United States, residing" at Thor, in the count-y of Humboldt and State Iowa, have invented a new and useful TireShield and Cieucherlrons Therefoi', of which she following is u specification This invention relates to the class of pneumatic ii es, and, more particularly to an im- .re shield or anti-skid and anti-Wear armor, and clencher irons or retaining means ihei'cfor, the object of the invention being to maize use of automobile tire casings or shoes oiiezthe some are no longer strong enough to wiihsiend. air pressure the device comprehending the use of the "worn casings by cu-fi the some nto sections of equal lengths, i' """i'eieoly in number for each iii-e, nov l in one being provided for mound ing the soil in posision as Well connect- 111;: end retaining them against displace and 1'50 take up wear and tear so to save the new "sire casings in addition to producing more eii'ici-ent traction between the tire and the road.

A further object of the invention is to provide improved shield embodying a pluralityof seciions arrenged in spaced ree so as to allow .mud or Waier some, so escape or fall .i novel means receiving the ciencher poriions of iJilSi-lfe casing sections the shield e "l for adjust-ably connecting is a they may be readily up idjneied is elves slightly vary ng ndoihei" objects in view the descripiion pro on. resides in the combineisngem ui of end in the is-- iciaion hereinafter described uimec, i; being understood i-hs'c Withscope of is cl imech changes 1n embodimentof the invention Fig. 3 is a perspective view of one of the Tclencher irons or retaining devices for mounting the sections of the shield on'the tire; and

Fig. i is e detail the device.

Referring to the drawings in detail, in which like reference characters designate 60 corresponding parts throughout the several views, my improved tire shield is shown as comprising a pluralit of sections produced by cutting en 0 d tire casing or shoe into a plurality of sections preferablyiof equal lengths, efter said casing or shoe is no longer able to Withstand the air pressure, said sections being provided with the usual clencher portions 11. The tire clencher irons or retaining devices for mounting the, shield or sections thereof, are designated at 12 and are in the form of curved strips or sections of mesel or {other suitable rigid immaterial, such as aluminum, sheet or cast malleableiron or th'e like with their end portions extended radially and flush with the ends of the sections 10, as particularly indicated in Fig.1 of the drawings. 7

These retaining devices are of substantielly the some cross-section as the clencher portions 11 but sufficiently large to provide therein, grooves 14 of similar cross section adapted to uccommodaize said clenchez' portions which ere slid into position longitudineily from one end of each iron or section. Thai is, each retaining device has a straight and fiat inner portion or face 15 and an outwardly directed outer portion 16 terminating in. s. fienge 1'7 curved inwardly and udepeed so conform to and overlie the bead of the clenchex portion 11 of ehesec tion of the "Worn out-jive UfiSlDg or shoe formin the shield or einiorf The portions 15 an 17 are spaced eperi: to provide slots 18 to accommodaie the ad'ecent portions of the tire sections 10, thus rmly gripping the latter and rigidly retaining the same in posiion, even though the same may be Worn, rim out, or cracked. Each fastening member 01 iron 12 is provided with a closed end well l9 and an 0 on end 20, said closed end serving" to limit tile displacement of the section of the shield at its clencher portion'll therein, in order that the ends of the shield of a link employed with other similar fastening means seefiions and. the remining members or irons will be flush] In order to assemble iler in position, the endslhereof are provided will; apertures 21 mizipteil'io reveive bolts or 22 for con nesting the eections in spzu o relatioin through the medium of inks '23. These links are :ipertnred at their en-tia end of each being provided with a plurality of apertures 2% providing an ;i.(l ,uswl)ie connection by which the L... may be male "0 apply to fires slightly varying in size or (liaeler. liy lnwin llie sections spaced apart the some will eerve as traction lugs or mitisiipping and skiilding elements to insure better grip or auction on. the roznl or friction between the armor and the road surface in addition to allowing any mud or water which may enter between the "tires and the seciiions of the shield n way 011%. that is, so the same may escape at the ends thereof. in "the ilrmvings, and especially in Fig. .i, the device is shown applied i0 a tire 25 mounted on the rim 26 of a. Wheel 27, The inner faces of the fiat portions 15 are preferably slightly offset inwardly bui snlr sian'tially in alineznent with the inner edge of the curved olenclier portion 17 of the re-- wining ineinbers or irons, tlins securely holding the elem-her poriions oi the section of. tire forming the shield The device "will Stop wear and tear on Hie new tire casing or shoe, will be instrumental to protecting the same against punctures and blowoiras, and, will inure greater mileage bin-neon,

1 ii. A. t re shield comprising H lnruli'l o'l sedaions consisting of a. tire shoe or one; ing of substantially equal lengths inning CltEHUliGi portions, retaining members con prising curved sections of rigid material having int inner portions? and outwardly oil'l'set iin'vzirclly curved onier poi-dons form- 4-: ing slots with gaiilinner portions. and grooves conforming to the shape of said rleneiier portions to reoeivo the latter new in longitiulinnlly. sniil retaining members kzli'll having one end oloseil and mljustnble 5% links connociing said. retaining members.
